Changeset 41820

Message:

Database: When parsing the host, leave the port and socket as null if they're not defined.

This fixes a change in behaviour introduced by [41629].

The host is set to an empty string when it isn't defined, this continues existing behaviour. In particular, the mysqli library treats a null host as being the same as localhost, which is not always the intended behaviour.

Props birgire, markjaquith, pento.
Fixes #41722.
